You know... i would really, really love to see more of the slots in the hotbar - toolbar.

I dont really see any reason why we should see only one line of item-icon slots. Besides, the place where you click to move them up and down, those small icons on the side - are really, really too small. So i have to aim every time i try that.

Wouldn't it be much better if we could see at least two rows of item and skills at once?
Maybe not all three but... at least two?

That would be easier to achieve, without enlarging the hotbar too much.
You would just need to make icons a bit smaller and the hotbar (toolbar) a bit bigger.

So icons would still be visible and easily recognizable while the hotbar-toolbar would not become too big and inelegant.
